I want to control bipolar motor with L297/L298 and an Arduino.
But I have a question about the L298: In the datasheet: Click Here
Turn-On and Turn-Off : Before to Turn-ON the Supply Voltage and before to Turn it OFF, the Enable input must be driven to the Low state.
How I can do that for the power ON ? Simply put the output of the arduino wich is connected to the L297 enable at LOW (and so, put the L298 at LOW because the L297 control the L298) ? But during the initialization of the arduino, the L298 will be already power on....
Or I can put a pulldown resistor on the L297's enable pin ?
Thanks for your answer, (Sorry for my english)
